3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 3536 apply.
4 Test conditions
Unless otherwise specified, the tests shall be carried out under the following conditions:
— Ambient temperature: 20 °C ± 5 °C;
— Atmospheric pressure: 86 kPa to 106 kPa (860 mbar to 1 060 mbar);
— Relative humidity: (60 ± 20) %.
5 Application of tests
For certain types of safety glazing materials, it is not necessary to carry out all the tests specified in this International Standard.
6 227 g ball test
Rigid plastic safety glazing materials can alternatively be tested in accordance with ISO 15082.
6.1 Principle
Determination of whether the safety glazing material has a certain minimum strength and cohesion under impact from a small hard object.
6.2 Apparatus
6.2.1 Hardness steel ball, with a mass of 227 g ± 2 g and a diameter of approximately 38 mm.
6.2.2 Means for dropping the ball freely from a height to be specified, or means for giving the ball a velocity equivalent to that obtained by the free fall. When a device to project the ball is used, the tolerance on velocity shall be ±1 % of the velocity equivalent to that obtained by the free fall.
6.2.3 Supporting fixture, such as that shown in Figure 1, composed of two steel frames, with machined borders, 15 mm wide, fitting one over the other and faced with rubber gaskets about 3 mm thick and 15 mm wide, of hardness 50 IRHD, determined in accordance with ISO 48. The lower frame rests on a steel box, about 150 mm high. The test piece is held in place by the upper frame, the mass of which is about 3 kg. The supporting frame is welded on a sheet of steel about 12 mm thick, resting on the floor, with an interposed sheet of rubber, about 3 mm thick, of hardness 50 IRHD.
7 2 260 g ball test
Rigid plastic safety glazing materials may alternatively be tested in accordance with ISO 15082.
7.1 Principle
Evaluation of the penetration resistance of the safety glazing material.
7.2 Apparatus
7.2.1 Hardened steel ball, with a mass of 2 260 g ± 20 g and a diameter of approximately 82 mm.
7.2.2 Means for dropping the ball freely from a height to be specified, or means for giving the ball a velocity equivalent to that obtained by the free fall.
When a device to project the ball is used, the tolerance on velocity shall be ±1 % of the velocity equivalent
to that obtained by the free fall.
7.2.3 Supporting fixture, as described in 6.2.3.
7.3 Test piece
The test piece shall be a flat square with 300 + mm sides or shall be cut out from the flattest part of a windscreen or other curved safety glazing material.BS ISO 03537 pdf download.
